Thread: 400whp, Whats needed?

hell jpsr20det made stupid power on race gas and meth with the roller rocker.

Are you just that dumb or high on some grade A crack

I think you should take break for a little that egg nog is making you loopy

ok then name 10-11 second quarter mile cars from the factory that are that fast? ready set go ......

lol dam u beat me to it............ I've come to find out 400whp is a bit slow for my taste actually.

Thanks to everyone who replied and it was actually helpful. From my view point it seems like once you pass 375-400whp you start to enter a new world where things start to becoming easy to fuck up, kinda like the point of no return, and the stock parts start to need to be replaced. What I am looking for is a quick DD at a single boost level on pump gas with a quick spooling turbo. I am starting to think a GT2860RS setup would be better suited for what I am looking for and lowering my power goals to 350whp. Do you guys believe I should be able to reach this goal on 93 pump at 15psi with S4 cams?

Ho Ho Ho Ho Merry Christmas Jamanrr

lol........ so u fix up a car to put a stock car to shame huh? a car with warranty and more comforts uh?

yes and 400hp is fun but i would rather have a fast spooling de+T on the streets

Use the GT2871R, with .86 ar turbine housing.

It will make the 350-370 WHP mark with JWT S4 cams at 15PSI with no problems . If you change your mind for more WHP then you will have it. It is always best to not run the turbo right at its power level peak as you tend to run high intake and exhaust temps.

350-360 WHP is pushing the GT28RS to its limit and they usally see that WHP at 16-17 PSI. It can make alot more with external wastegate but keeping things simple with internal wastegate is the way to go for what you want.


GT2871R for the win

probably but when you're into boost you're going to want more once u max out ur set up hence why alot of poeple were saying to just fork out a litle more and go with the 2871 and have room for improvement....
